Examples with EvaluationVisitor org.apache.drill.exec.expr.EvaluationVisitor used on opensource projects

Example 1 with EvaluationVisitor

use of org.apache.drill.exec.expr.EvaluationVisitor in project drill by apache.

the class TestEvaluationVisitor method x.

@Test
public void x() throws Exception {
    DrillConfig c = DrillConfig.create();
    FunctionImplementationRegistry reg = new FunctionImplementationRegistry(c);
    EvaluationVisitor v = new EvaluationVisitor(reg);
    CodeGenerator<?> g = CodeGenerator.get(Projector.TEMPLATE_DEFINITION, reg, null);
    SchemaPath path = (SchemaPath) getExpr("a.b[4][2].c[6]");
    TypedFieldId id = //
    TypedFieldId.newBuilder().addId(//
    1).addId(//
    3).remainder(//
    path.getRootSegment()).intermediateType(Types.optional(MinorType.MAP)).finalType(//
    Types.repeated(MinorType.MAP)).hyper().withIndex().build();
    ValueVectorReadExpression e = new ValueVectorReadExpression(id);
    TypedFieldId outId = //
    TypedFieldId.newBuilder().addId(//
    1).finalType(//
    Types.repeated(MinorType.MAP)).intermediateType(//
    Types.repeated(MinorType.MAP)).build();
    ValueVectorWriteExpression e2 = new ValueVectorWriteExpression(outId, e, true);
    v.addExpr(e2, g.getRoot());
    logger.debug(g.generateAndGet());
}
